Hi! We are using Samba 3.0.22 PDC and 2 Samba 3.0.28 BDC with ldapsam based backend. Since about one week, the domain admin (admin) has no admin rights on the XP/2003 machines any more and I don't have an idea why. Can somebody please help me? Some tests and configurations: # id admin uid=0(root) gid=0(root) Gruppen=0(root),998(ldapadmin) # net groupmap list Domain Admins (S-1-5-21-8915387-1074272342-1703228666-512) -> ldapadmin Domain Users (S-1-5-21-8915387-1074272342-1703228666-513) -> ldapuser # ldapsearch -x uid=admin # extended LDIF # # LDAPv3 # base <> with scope subtree # filter: uid=admin # requesting: ALL # # Admin, Users, xxxxxxx.ac.at dn: uid=Admin,ou=Users,dc=xxxxxxxx,dc=ac.at objectClass: account objectClass: posixAccount objectClass: shadowAccount objectClass: sambaSamAccount sambaPwdMustChange: 2147483647 sambaLogoffTime: 0 sambaLogonTime: 0 sambaKickoffTime: 0 description: sambaDomainName: XX_XXX uid: Admin cn: Admin displayName: Admin sambaSID: S-1-5-21-1992494304-3358384209-1871445459-1000 uidNumber: 0 homeDirectory: /root loginShell: /bin/false shadowLastChange: 12529 sambaLogonScript: ver_nsc.cmd gidNumber: 0 sambaPrimaryGroupSID: S-1-5-21-1992494304-3358384209-1871445459-512 sambaProfilePath: //XX.XX.XX.XX/profiles/Admin sambaPwdCanChange: 1156912744 sambaPasswordHistory: 00000000000000000000000000000000000000000000000000000000 00000000 sambaPwdLastSet: 1156912744 sambaAcctFlags: [U ] # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 cat /etc/samba/smb.conf [global] # NAME SETTINGS netbios name = xxxxx server string = xxxxx workgroup = xxxxx # SECURITY SETTINGS os level = 255 preferred master = yes domain master = yes local master = yes domain logons = yes security = user encrypt passwords = yes # min passwd length = 6 announce version = 7 announce as = NT admin users = @"Domain Admins",admin,Admin # PRINTER SETTINGS printing = BSD load printers = No disable spoolss = Yes show add printer wizard = No # LDAP SETTINGS ldap admin dn="uid=Admin,ou=Users,dc=xxxxxx,dc=ac.at" # ldap ssl = start_tls ldap ssl = no passdb backend = ldapsam ldap delete dn = no ldap user suffix = ou=Users ldap group suffix = ou=Groups ldap machine suffix = ou=Clients ldap suffix = dc=xxxxxxx,dc=ac.at # ldap filter = (&(uid=%u)(objectclass=sambaSamAccount)) ldap passwd sync = yes
